Answer: OPTION B
Step-by-step explanation:
You can observe in the graph of the function given, it begins to decrease from --3π/2 to -π/2. Then it increases again to y=3, where it reaches it maximum point, this is when x=kπ/2 (With k an odd integer: 1,3,5,7...)
Finally, it begins to decrease again from π/2 to 3π/2.
Therefore, the answer is the option B.
These three roots are sufficient to enable us to form a 3rd degree polynomial:
f(x) = (x+4)(x-4)(x-2) = (x^2 - 16)(x-2) = x^3 - 2x^2 - 16x + 32 (answer)
Answer:
a is the answer
Step-by-step explanation:
a is the answer because the way they are being multiplied are consistent, while the others arent.
Answer:
9/41
Step-by-step explanation:
Cosine represents adjacent / hypotenuse.
When A is the reference angle, AB is the adjacent side (9) and AC is the hypotenuse (41).
9/41 is already simplified.
